NEED help with a math question QUICK please?
At the end of a certain year, the four companies with the largest number of home Internet users in the United States were Microsoft, Time Warner, Yahoo, and Google, with a combined audience of 284 million users. Taking x to be the Microsoft audience in millions, y the Time Warner audience in millions, z the Yahoo audience in millions, and u the Google audience in millions, it was observed that
z − u = 3(x − y) + 6
x + y = 50 + z + u
and x − y + z − u = 42.
How large was the audience of each of the four companies at the end of that year?

x=88, y=79, u=42, z=75
I solved it by using a 4x4 equation solver online.
